Hedonic Scale

The 9-point hedonic scale, also known as degree-of-liking scale, is the most common hedonic scale for measuring product liking by consumers.

Differently coded samples are presented to
consumer panelists one at a time and they are asked to rate their
hedonic response on the scale that can be in a vertical or horizontal
line without affecting results.

The hedonic scale is based on equal interval,
which is important in the assignment of numerical values to the response
choices (from 1 = “dislike extremely” to 9 = “like extremely”) and to
the use of parametric statistics in analysis of the data.
